Title: Oxygen controlling system for multi-fuel combustion
Inventor: HISAYOSHI GI
IPC: F23N5/18
Filed: 1981-08-28
Abstract: PURPOSE:To effectively control the rate of residual oxygen to get an ideal rate, by finding the rate of residual oxygen to the mixing ratio of both fuel from a compensating coefficient to the mixing ratio of both fuel and a suitability value in the aspect of residual oxygen of both fuel, in an industrial combustion furnace in which two kinds of fuel are used. CONSTITUTION:When heavy oil and gas are mixed and burnt together, the flow rates of both oil and gas are detected by detectors 3 and 4, respectively, and a calorific value is compensated by compensators 6 and 7. Then, the mixing ratio of heavy oil to gas is found by a calculator 8, and a compensating coefficient to the mixing ratio is calculated by a function calculator 9. Both outputs from compensators 6 and 7 are added up by an adder 11, and a suitability value in the aspect of residual oxygen to the added value is calculated by a function calculator 10. Next, the rate of residual oxygen to the mixing ratio of both fuel is calculated by a multiplier 12 by multiplying the outputs from both function calculators 9 and 10, and the result is used as a setting value to a controller 14 to calculate the rate of oxygen. An air-fuel controller 16 is controlled by an output from the controller 14, by the intermediary of an arithmetic circuit 15 to compensate an air-fuel ratio.

Abstract: PURPOSE:To obtain high sensitivity on detecting the unbalance of phase voltage by comparing the potential differences of the respective neutral points of a three-phase balanced load having no delay element and a three-phase balanced delay load having a delay element, with each other. CONSTITUTION:When the unbalance of phase voltage is generated, then voltage is generated at the neutral point of a Y-connection balance circuit 2, but at the neutral point of a Y-connection balance delay circuit 3, within a delay time, the voltage is not generated, and so at both ends of a resistor 4, voltage according to the potential difference of the neutral point is generated. This voltage is full-wave-rectified by a rectifying bridge circuit 5, and a photo-coupler 6 is turned ON. In this case, in a transistor 8 in an ON-state, base voltage is turned into zero, and so the transistor 8 is turned OFF, and when the OFF- state is kept for a fixed time, then a retaining circuit 11 is changed to come to a level 'H' from a level 'L', and the level 'H' is retained as it is. As a result, detecting the phase voltage unbalance of a power source works a safety circuit 12.
